Incidence and Risk Factors for Right Ventricular Outflow Tract Obstruction after the Arterial Switch Operation
Key result
The arterial switch operation was associated with an 11% incidence of right ventricular outflow tract obstruction requiring reintervention, driven by risk factors like side-by-side great arteries (P<0.001).
Why the study?

Population
688 patients who underwent the arterial switch operation (ASO) between 1983 and 2014
Design
Cohort
Follow-up
up to 25 years

Implication
May warrant morphology-specific surveillance after arterial switch; leaves open optimal prevention strategies in prospective cohorts.

Right ventricular outflow tract obstruction is a significant long-term complication after the arterial switch operation, particularly in patients with complex morphology or high discharge gradients.
Cite This Study
Vitanova et al. (2018) conducted a cohort in Post-arterial switch operation (n=688). Arterial switch operation and associated risk factors was evaluated on Right ventricular outflow tract obstruction (RVOTO) requiring reintervention. The arterial switch operation was associated with an 11% incidence of right ventricular outflow tract obstruction requiring reintervention, driven by risk factors like side-by-side great arteries (P<0.001).
